Laguna Lo Custodio, Natural lagoon in Concepción, Chile

Laguna Lo Custodio is a natural water body in the northern part of Concepción covering 3.4 hectares. It has a sandy bottom and remains shallow, reaching less than 1.5 meters deep in most areas.

This water body formed between 8,000 and 6,400 years ago through the interaction of river and wind processes. The Bío Bío River's movement and behavior shaped its development.

The lagoon takes its name from the Lo Custodio family, a surname tied to the land where it lies on the slopes of Cerro La Pólvora. It is one of seven lagoons on the northern side of the Bío Bío, alongside Price, Redonda, Las Tres Pascualas, Lo Méndez, Lo Galindo and La Pineda, and the smallest of them at 3.4 hectares.

This lagoon can be reached through multiple paths from downtown Concepción. A recreational park and multipurpose court nearby offer additional activities for visitors.

Laguna Lo Custodio is the smallest of the seven lagoons of Gran Concepción, covering just 3.4 hectares with a length of 80 metres. It lies close to the Lo Méndez and Lo Galindo lagoons on the slopes of Cerro La Pólvora.
